Current Problem with (Bustek configured) SCSI Host Adapters and American
Megatrends Motherboards

With ISC 3.0.1., a Bustek 742A SCSI Host Adapter or an American Megatrends
SCSI Host Adapter will fail when a Bustek 742A kernel is made and the
system restarted.

There is no immediate work-around for the Bustek controller, but with the
American Megatrends SCSI Host Adapter, the following configuration
settings should be entered as the Bustek kernel configuration information:

INT = 11
Primary Port Address = 330
Primary Memory Address = C800
DMA = 5

and the device table should be filled in with the device type at the
requested SCSI id. The American Megatrends SCSI Controller should be
configured accordingly.

According to Interactive (as of Friday, August 21, 1992), they will be
shipping, on request only, a Bustek driver update to any customer that
will correct this problem with the Bustek controller and the American
Megatrends controllers.

We are waiting for the new driver files from Interactive to arrive so that
we can begin testing.
